Title: Hollow cathode
Inventor: TAKAGI KENICHI
IPC: H01J1/20
Filed: 1988-06-24
Abstract: PURPOSE:To provide a cathode with less evaporation of filament and good durability by enclosing the filament with a cylindrical heat shield, and by providing an electron emitting substance such as barium oxide at that portion of heat shield inner surface which faces the filament. CONSTITUTION:Current is fed to a cathode 1 of a filament 2 installed in a vacuum chamber into which electric discharge gas is introduced, and electric discharge is generated between the cathode 1 and anode 9, and when electrons are supplied there plasma is generated, in which the discharge gas is electrically dissociated to generate ions. This cathode 1 is enclosed with a cylindrical heat shield 3. This is therefore free of plasma impact from surroundings, and provision of electron emitting substance 4 on the inner surface of this heat shield permits generation of a large quantity of electrons when electrons rush thereto from the cathode 1, to bring about electron propagation. Thereby a large quantity of electrons are obtained only by heating the cathode 1 at a low temp., contributing to prevention of the cathode from evaporation to enable service for a comparatively long time.

Abstract: PURPOSE:To prevent the deterioration in the reliability due to temperature rise of a fluorescent face of a cathode ray tube by controlling energy for driving the cathode ray tube so as to control the temperature of a coolant not to be in excess of a prescribed limit when a temperature detected by a temperature sensor of the coolant exceeds a prescribed limit. CONSTITUTION:A temperature of a coolant 7 sealed between a cathode ray tube 5 and a 1st lens 61 is measured and when the temperature of the coolant 7 gets higher, a brightness limit circuit 3 is controlled to decrease the energy for driving the cathode ray tube. Since the energy for driving the cathode ray tube (beam current) is decreased, the temperature of the fluorescent face is reduced and the temperature of the coolant 7 is decreased. When the temperature of the coolant 7 is reduced to a reference temperature or below, the limit of the brightness is released and the energy for driving the cathode ray tube is restored and the temperature of the fluorescent face of the cathode raw tube 5 rises and the deterioration in the reliability is prevented.

Filed: 1999-06-02
Abstract: PROBLEM TO BE SOLVED: To improve the operation of a sequential retrieval unit by making a retrieval unit retrieving energy at the next retrieving position of the next Walsh symbol when the existence of a signal is confirmed at a specific retrieving position of a Walsh symbol that is not located at the boundary of a power control group and to retrieve it at a retrieving position that is the same as the preceding one of the next Walsh symbol when it is not confirmed. SOLUTION: A retrieval unit retrieves energy at a specific retrieving position of read symbol data (s2) and confirms if it is equal to or more than upper limit that is perliminarily set (s5). If it is not equal to or more than the upper limit, it confirms if it is lower limit (s7). And, if it equals to or less than the lower limit, the retrieval unit records that a signal is not detected at the corresponding retrieving position (s8). When a retrieval result is neither equal to or more than the upper limit nor equal to or less than the lower limit and when the existence of a signal is not decided, it is confirmed whether the current retrieving position is the boundary of power control group (s9). If it is not the boundary, it returns to (s2) and checks energy at the same retrieving position of the next Walsh symbol.
